Cucumber是一个BDD测试框架，用于编写易于理解的测试用例。在Android应用程序测试中，可以使用Cucumber和Appium结合进行自动化测试。当需要在同一会话中运行多个Cucumber场景时，可以使用以下步骤：

1. 首先，在测试中设置一个全局的driver对象，以便在不同的场景之间共享它。

public class AppiumSetup {
    
    public static AppiumDriver driver;
    
    @BeforeClass
    public static void setUp() throws MalformedURLException {
        
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Android Emulator");
        capabilities.setCapability("platformVersion", "9.0");
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("appPackage", "com.example.testapp");
        capabilities.setCapability("appActivity", "MainActivity");
        
        URL url = new URL("http://127.0.0.1:4723/wd/hub");
        driver = new AndroidDriver(url, capabilities);
    }
    
    @AfterClass
    public static void tearDown() {
        driver.quit();
    }
}

2. 接着，在每个Cucumber场景的步骤之间共享该driver对象。

public class MyStepdefs {
    
    public static AppiumDriver driver;
    
    @Before
    public void setUp() {
        // 设置driver，以便在不同的场景之间共享它
        driver = AppiumSetup.driver;
    }
    
    @Given("^user is on the home screen$")
    public void userIsOnTheHomeScreen() {
        // 在主屏幕上进行操作
        MobileElement homeButton = driver.findElement(By.id("home_button"));
        homeButton.click();
    }
    
    @When("^user enters username and password$")
    public void userEntersUsernameAndPassword() {
        // 输入用户名和密码
        MobileElement usernameField = driver.findElement(By.id("username_field"));
        MobileElement passwordField = driver.findElement(By.id("password_field"));
        usernameField.sendKeys("user123");
        passwordField.sendKeys("password123");
    }
    
    @Then("^user should be logged in$")
    public void userShouldBeLoggedIn() {
        // 验证用户是否登录成功
        MobileElement loggedInMessage = driver.findElement(By.id("logged_in_message"));
        assertEquals("Welcome, user123", loggedInMessage.getText());
    }
}

通过以上步骤
